Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 9, in the utility model embodiment, a kind of cam bawl gapless index dial structure, comprise cam curved surface 203, casing 021, rotating disk 022, bearing 024, eccentric bearing block 020, cam power shaft 211, needle bearing 212 and output shaft 213, be provided with in described casing 021 and column 025 and eccentric bearing block 020 are installed, and the center line installing column 025 is mutually vertical with the center line of eccentric bearing block 020, wherein eccentric bearing block 020 installs cam power shaft 211, install on column 025 and output shaft 213 is installed, between the inwall of described output shaft 213 and installation column 025, interference fit is provided with bearing 024, output shaft 213 can freely be rotated, and the top of output shaft 213 to be connected rotating disk 022 by screw,
The outer surface of described output shaft 213 is provided with a circle needle bearing 212, and needle bearing 212 engages with the cam curved surface 203 of cam power shaft 211, thus forms the connection of cam bawl blind-mate.
Described cam power shaft 211 is processed into cam-type power shaft, and cam has any 360 degree of rotations uniform velocity curved surface (cam curved surface 203);
